Boss 321 . Two ends of the second hinge shaft 36 respectively pass through the boss 321 and are located inside the groove wall of the groove 35 . The boss 321 can rotate around the second hinge shaft 36 . The boss 321 is plugged and rotatably matched with the groove 35, and the boss 321 does not occupy external space, so that the overall shape of the multi-section second connecting rod 32 is beautiful.
具体地，凹槽35的两侧壁上分别设有第二通孔314，凸台321设有与第二通孔314位置对应的第二圆孔，第二铰接轴36的两端分别穿过第二圆孔且位于第二通孔314内。Specifically, the two side walls of the groove 35 are respectively provided with second through holes 314, and the boss 321 is provided with a second circular hole corresponding to the position of the second through holes 314, and the two ends of the second hinge shaft 36 respectively pass through The second circular hole is located in the second through hole 314 .
第一连杆31的凹槽35的两侧槽壁上还设有位于第二通孔314一侧且与第二通孔314连通的第二缺口315，以及位于第二缺口315两侧的第二螺纹孔316。第二通孔314的内径与第二缺口315的宽度有关，第二缺口315的宽度大，即第二缺口315开合程度大，则第二通孔314的内径大，第二缺口315的宽度小，则第二通孔314的内径小。由于第二铰接轴36位于第二通孔314内，第二连杆32需要绕第二铰接轴36转动，为了使第二铰接轴36平稳设置在第二通孔314内，要求第二通孔314卡住第二铰接轴36的同时凸台321能绕第二铰接轴36转动。为了便于调节第二通孔314的内径，在第二螺纹孔316内设有第二调紧螺钉，拧紧第二调紧螺钉，可使第二缺口315的宽度变小，即使第二通孔314靠近第二缺口315部位的内径变小，使第二通孔314卡住第二铰接轴36。The groove walls on both sides of the groove 35 of the first connecting rod 31 are also provided with a second notch 315 located on one side of the second through hole 314 and communicating with the second through hole 314 , and a second notch 315 located on both sides of the second notch 315 Two threaded holes 316. The inner diameter of the second through hole 314 is related to the width of the second notch 315. If the width of the second notch 315 is large, that is, the degree of opening and closing of the second notch 315 is large, the inner diameter of the second through hole 314 is large, and the width of the second notch 315 is large. is small, the inner diameter of the second through hole 314 is small. Since the second hinge shaft 36 is located in the second through hole 314, the second connecting rod 32 needs to rotate around the second hinge shaft 36. In order to make the second hinge shaft 36 stably arranged in the second through hole 314, the second through hole is required to 314 blocks the second hinge shaft 36 while the boss 321 can rotate around the second hinge shaft 36 . In order to facilitate the adjustment of the inner diameter of the second through hole 314, a second adjusting screw is provided in the second threaded hole 316, and the second adjusting screw can be tightened to make the width of the second notch 315 smaller, even if the second through hole 314 The inner diameter of the portion close to the second notch 315 becomes smaller, so that the second through hole 314 clamps the second hinge shaft 36 .
除了在第一连杆31的凹槽35的两侧壁上设置第二缺口315、第二螺纹孔316及第二调紧螺钉外，还可在第二连杆32的凹槽35的两侧壁上设置第二缺口315、第二螺纹孔316及第二调紧螺钉，用于保证每一个第二铰接轴36平稳设置且保证每一个凸台321平稳转动。In addition to setting the second notch 315, the second threaded hole 316 and the second adjusting screw on the two side walls of the groove 35 of the first connecting rod 31, the two sides of the groove 35 of the second connecting rod 32 can also A second notch 315 , a second threaded hole 316 and a second adjusting screw are provided on the wall to ensure that each second hinge shaft 36 is stably set and each boss 321 rotates smoothly.
参阅图1或图3，作为本实用新型提供的螺纹紧固件拆装装置的一种具体实施方式，转动手柄33为长杆状结构，转动手柄33的两端分别穿过尾节第二连杆32的凹槽35及第二通孔314。Referring to Fig. 1 or Fig. 3, as a specific embodiment of the threaded fastener dismounting device provided by the present invention, the rotating handle 33 is a long rod-shaped structure, and the two ends of the rotating handle 33 respectively pass through the second connection of the tail joint. The groove 35 and the second through hole 314 of the rod 32 .
参阅图1至图4，作为本实用新型提供的螺纹紧固件拆装装置的一种具体实施方式，连接耳20上套设有限位块40，限位块40用于限定操作杆30摆动的角度。具体地，可在一个连接耳20上套设限位块40，也可在两个连接耳20上分别套设一个限位块40。Referring to Fig. 1 to Fig. 4, as a specific embodiment of the threaded fastener dismounting device provided by the present invention, the connecting ear 20 is provided with a limit block 40, and the limit block 40 is used to limit the swing of the operating rod 30. angle. Specifically, a limiting block 40 may be sleeved on one connecting ear 20 , or a limiting block 40 may be sleeved on two connecting ears 20 respectively.
限位块40与连接耳20为滑动连接，具体的实现方式为，连接耳20上设有导轨21，导轨21的设置方向与套筒10的轴向平行。限位块40具有用于使连接耳20及操作杆30穿过的内腔，内腔的腔壁与导轨21滑动连接。The limit block 40 is in sliding connection with the connecting ear 20 , and the specific implementation method is that the connecting ear 20 is provided with a guide rail 21 , and the installation direction of the guide rail 21 is parallel to the axial direction of the sleeve 10 . The limit block 40 has an inner cavity for the connecting ear 20 and the operating rod 30 to pass through, and the cavity wall of the inner cavity is slidably connected with the guide rail 21 .
限位块40套设于连接耳20上，可于连接耳20上滑动，用于限定操作杆30摆动的角度。限位块40可滑至连接耳20与操作杆30的铰接处的两侧，当限位块40位于铰接处的靠近套筒10的一侧，操作杆30绕铰接点摆动，直至其侧面与限位块40的端面接触为止，如图3或图4所示。当限位块40位于铰接处的另一侧，操作杆30的端部穿过限位块40或位于限位块40内，限位块40限制操作杆30摆动，如图1所示，此时操作杆30的中心线与套筒10的中心线平行。限位块40用于限定操作杆30转动角度，避免操作杆30转动过渡而影响对其施力。The limiting block 40 is sheathed on the connecting ear 20 and can slide on the connecting ear 20 to limit the swing angle of the operating rod 30 . The limit block 40 can slide to both sides of the hinge between the connecting ear 20 and the operating rod 30. When the limit block 40 is located at the side of the hinge close to the sleeve 10, the operating rod 30 swings around the hinge point until its side and until the end surfaces of the limiting block 40 touch, as shown in FIG. 3 or FIG. 4 . When the limit block 40 is located on the other side of the hinge, the end of the operating rod 30 passes through the limit block 40 or is located in the limit block 40, and the limit block 40 limits the swing of the operating rod 30, as shown in Figure 1, here When the centerline of the operating rod 30 is parallel to the centerline of the sleeve 10 . The limit block 40 is used to limit the rotation angle of the operating rod 30 , so as to prevent the operating rod 30 from being affected by the excessive rotation of the operating rod 30 .
